Alkreflex® Roof 1.7

Alkreflex® Roof 1.7 is a multi-layer insulating breathable membrane. It is waterproof, breathable, insulating and space-saving. Extremely suitable for application where adjustments of gutter and fascia due to the thickness may not or hardly be adjusted, such as with monuments or terraced houses. Alkreflex® Roof 1.7 consists of a core of high density wool sealed by two vapour permeable membranes. The bottom layer contributes to the overall thermal resistance of the structure through reflection of thermal radiation (infrared). Alkreflex® Roof 1.7 contains no stitching which prevents air or moisture leaks. Alkreflex® Roof 1.7 is an efficient and effective insulation solution with low space loss.

For optimal results, it is recommended that the reflective layer be kept at least 20 mm clear of the substrate.
